horiontal' ledges at the upper and lower- `portions thereof, and the matrices are provided with ears or lugs at the upper and lower ends thereof adapted to coperate respectively with the said horizontal ledges of the support or slide,`the vears cr upper ends of the matrix being adapted to slide and rest upon the uppermost-horizontal ledge to support the'matrix at its'lowe'rmos't level, and the lugs or ears at the lower end of the matrix being adapted to be engaged with and rest upon the lower horizontal ledge to support the matrix in its uppermost adjusted position. This' yarrangement pre1 sents the defect, that the alinement of the letters in the cast line when cast from 'raised matrices is soon rendered irregular,ias the bottom faces of the lower ears or lugs of the vmatrices become worn away much more vrapidly than the other supporting faces of the matrices since each matrix constantly and repeatedly drops and strikes with its lower ears or lugs various machine parts and the other matrices, and when raised it is exclusively guided by its lower-ears nearly during its entire passage through the ma.- chine. The matriceswith two or ,more superposed intaglio' letters are 'supported on the bottom facesv of their upper ears or lugs like ordinary matrices with single intaglio letters only in case their vlupper or uppermost intaglio letters are used for casting the linotypes. When the lower intaglio letters or characters are linotypes, ofcourse, the respective. matrices require to be raised into their upper or any"y lugs at the to be` used for casting the Specification of Letters Patent.

Serial No. 39,717. l i l I of the upper positions, so that the -bottoml faces of their up'per ears remain at a height above'the guiding shoulders of the slide, second elevator, or other device, and consequently the respective-,ledge or ledges in the device will have to engage beneath the lower rear ears of the matr1ces for supporting and guiding the latter. yIt is thus obvious, that after the bottom'lfaces of the lowerI ears have been more or lessworn away the several letter's of characters in the linotype cast from raised matrices will no longer be alined, they being more or less lowered in proportionl tothe wear of the bottom faces of the lower rear lugs of the respective matrices. As the intaglio letters in the matrices representing beingv employed'muclrmore than the other or anyof the others, it follows, that the respective matrices are not used uniformly and consequently their lower rear lugs will beirregul'arly worn away For this reason also the alinement of the -letters in the cast linotype cannot be maintained any longer. It has heretofore been proposed to remedy this defect by providing the'slide or support for the composed matrices, with a flange extending inwardly beyond the plane of the edges of the matrices and vadapted to support the matrices by contact with the por- -tion of the lower ends thereof' within said plane. But such a construction necessitates the 'cuttingaway of the space bars so that the matrices and space barsI are of unequall The'invention will be understood from the following detail description when considered in connection with the 'accompanying drawings wherein I'have illustrated a preferred embodimentthereof.

Inthe drawings: Figure 1 is a vertical cross section -throughr a part of -aV mold wheel, the mold, and the slide or first elesav l dierent fonts are used differently one fo'nt vater or vother device in a plane adjacent a nudi-riaY occupying its lower position, While another n'zatrix behind the same occupied its upper position, all of the matrices being assembled to be provided with only two super posed intaglio letters or characters. Fig. "Z is similar section in another plane adiale another matrix behind the same 0clower position.. Fig. 3 is a side ion of one of the matrices. Fig. l one the space bars, and F 5 is a non taken onr the-line 5 5 of'Fig. 3.

in accordance with the present invent-ion, the spacedopposing walls of the slide or device 3 are provided with superposed grooves' i. The matrices are provided at their upper ends with oppositely disposed ears or lugs 5, the yheight of which is less than'the dileience in level of the plural characters 6 of the nmtrices,said ears or lugs being adapted to he engaged with the upper grooves 4 `with theirunder faces 5 resting upon the lower 1 Walls if thereof to support the matrices in position to cast type from the-lower' character thereon and to'be engaged with the lower set'oi' grooves 4 with. their lower faces 5 "resting upon the lower walls 4 thereoll to Asupport the matrix in position to cast from.

the upper character thereon.

lt will be remarked that the support for the .matrices at the different levels to which theya're adapted to be adjusted is provided through the single pair of ,ears 5 at the upper end or" the matrix entirely removed from and independent of the bottom face of the matrix, and which practically undergo no'wear or tear so that the alinement of the characters is assured. lt will also be 0b.- served that the supporting ledges of the slide or supportipr thecomposed line ot 'matrices are within the vertical plane of the opposing walls of the slide, and that this v construction does not necessitate the recessing of thematrices, or the special formation lor cutting' awayof the' space bars theuse of ears d', said ears being shown somewhatspace bars and" matrices 'of equal width being permitted.

In the particular cons tmction illustrated v vided with two superposed characters and the support or slide Vwith two sets of 4L. When the matrices are provided Witha' a-niatri; occupying its upper position,

grooves greater number ot' superposed characters the sets of grooves are correspondingly in creased.

I desire it to be understood that modifications and changes in the particular construction illustrated in the drawings as will appeal to those skilled in the art and falling within the scope of the appended claims may be made Without departing Afrom the spirit of the inventiom What l claim-is:

l. In alinotype machine, the combination with amati-ix provided with a plurality ot' characters' at different heights and having a pair of oppositely disposed ears oi equal height at its upper end, of a device for presenting matrices to the mold, ysaid device having spaced opposing Awalls each iprovided with a plurality of superimposed grooves extending longitudinally thereof, the grooves or' the opposing walls being arranged to provide sets of parallel grooves at diilerent heights adapted to receive the ears at the upper end of the matrix, the under faces of said ears being adapted t0 rest upon thelower walls of the'grooves and the being arranged to provide parallel sets of grooves 'at different heights adapted to receive the ears at `the upper end of the matrix, the under 'faces of the ears being adapted to yrest upon the lower walls of the grooves,V and the lower walls of the grooves constituting supporting ledges to sustain the matrices at the different heights to which A it is adapted to be adj usted, and space bars of a Width equal the Width ofthe matrices.

3. In a linotype machine, a' matrix'having a plurality of .character indentations in one edge and provided with a, pair of voppositely disposed ears at its upper-end, said ears projecting laterally from the sides of the main body portion of the matriX,-in combi-nation with a mold, and 'a device for presenting matrices to the mold, said devine having spaced opposing walls -each provided With av plurality of superimposed grooves extending longitudinally thereof, the grooves of the opposing Walls being arlranged Vto provide sets of parallel lgrooves at diderent heights and adapted' to4 .receive the* ears at the. upper end of the' matrix,

Jill@ dit@ the under faces of the ears being adapted to restlupon the lower walls of the grooves; and the lower walls of the grooves consti tuting supporting ledges to sustain the Ina.-4 triX at the diferent lengths at'which it is adapted to be adjusted, the supporting ears at the upper end of the matrix being ofequal width' and height, and of less vheight than the distance between the matrix characters.

In testimony whereof I affix my signature in presence of two witnesses.
